By exploring common themes in the lives and works of logician Kurt Gödel, artist M. C. Escher and composer Johann Sebastian Bach, GEB expounds concepts fundamental to mathematics, symmetry,
and intelligence. Through illustration and analysis, the book discusses
how self-reference and formal rules allow systems to acquire meaning
despite being made of "meaningless" elements. It also discusses what it
means to communicate, how knowledge can be represented and stored, the
methods and limitations of symbolic representation, and even the
fundamental notion of "meaning" itself.
